Andy,

you may well be correct. I've never been to DRS in person, and only picked up on what they claimed to have on the webpage that you shared earlier in this thread. As you and I have discussed many times, actually getting an entire H2S "working" is probably near impossible - for one thing multi-kW pulses radiating on the 3GHz bands is not likely to be popular these days, and I suspect Ofcom (and no doubt H & S!) would be on the case rather quickly! So somewhere simulation has to take a major role.

Likewise with their GEE system. That being much simpler I can well imagine they got the airborne side working OK, with the ground stations being simulated. That is vastly easier to do. I do have one of their GEE ground station simulators half-built on the shelves here.
